# commit 86125df731cb260f425b852ec0c672ac12449d31
# Merge: a74aa96 d55bac2
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Wed Jul 11 12:44:07 2018 -0700
# 
#     Merge branch 'for-4.18-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
#     
#     Pull libata fixes from Tejun Heo:
#     
#      - Jens's patches to expand the usable command depth from 31 to 32 broke
#        sata_fsl due to a subtle command iteration bug. Fixed by introducing
#        explicit iteration helpers and using the correct variant.
#     
#      - On some laptops, enabling LPM by default reportedly led to occasional
#        hard hangs. Blacklist the affected cases.
#     
#      - Other misc fixes / changes.
#     
#     * 'for-4.18-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
#       ata: Remove depends on HAS_DMA in case of platform dependency

#       ata: Fix ZBC_OUT command block check
#       ahci: Add Intel Ice Lake LP PCI ID
#       ahci: Disable LPM on Lenovo 50 series laptops with a too old BIOS
#       sata_nv: remove redundant pointers sdev0 and sdev1
#       sata_fsl: remove dead code in tag retrieval
#       sata_fsl: convert to command iterator
#       libata: convert eh to command iterators
#       libata: add command iterator helpers
#       ata: ahci_mvebu: ahci_mvebu_stop_engine() can be static
#       libahci: Fix possible Spectre-v1 pmp indexing in ahci_led_store()
